Please give me the answer and show me how you solved it

the slope is -5 and y intercept is (0,2)

Step-by-step explanation:

the slope intercept form is y=mx+b

m=slope. b=y intercept

find the values of M and B using the slope intercept formula like this

y=mx+b

m=-5

it helps if you graoh it as well

b=2

If sin y = 7/q and tan y= 7/r then the value of cos y is

Solution:

The values of sin y and tan y are given as 7/q and 7/r respectively.

We know the relationship between tan cos and sin which is

 --- equation 1

Since we already know the values of sin y and tan y we can easily find the value of cos y by substituting the values in eq1

Taking cos y to the other side of the equal to sign we get

Hence the value of cos y is
